phan/phan 2.2.4

Release 2.2.4 supporting PHP 7.0-7.3 syntax

on PHP Packagist

New features(CLI, Configs):

• Warn if any of the files passed in --include-analysis-file-list don't exist.

New features(Analysis):

• Reduce false positives inferring the resulting type of $x++, --$x, etc. (#2877)
• Fix false positives analyzing variable modification in elseif conditions (#2878, #2860)
  (e.g. no longer emit PhanRedundantCondition analyzing elseif ($offset = (int)$offset))
  (e.g. do a better job inferring variables set in complex if condition expressions)
• Warn about suspicious comparisons (e.g. new stdClass() <= new ArrayObject, 2 >= $bool, etc.) (#2892)
• Infer real union types from function/method calls.
• Don't emit the specialized *InLoop or *InGlobalScope issues for --redundant-condition-detection
  in more cases where being in a global or loop scope doesn't matter (e.g. if (new stdClass()))
• Be more accurate about inferring real union types from array destructuring assignments. (#2901)
• Be more accurate about inferring real union types from assertions that expressions are non-null. (#2901)
• Support dumping Phan's internal representation of a variable's union type (and real union type) with '@phan-debug-var $varName' (useful for debugging)
• Fix false positive PhanRedundantCondition analyzing if ([$a] = (expr)) (#2904)
• Warn about suspicious comparisons that are always true or always false, e.g. the initial check for for ($i = 100; $i < 20; $i++) (#2888)
• Emit PhanSuspiciousLoopDirection when a for loop increases a variable, but the variable is checked against a maximum (or the opposite) (#2888)
  e.g. for ($i = 0; $i <= 10; $i--)
• Emit critical errors for duplicate use for class/namespace, function, or constant (#2897)
  New issue types: PhanDuplicateUseNormal, PhanDuplicateUseFunction, PhanDuplicateUseConstant
• Emit PhanCompatibleUnsetCast for uses of the deprecated (unset)(expr) cast. (#2871)
• Emit PhanDeprecatedClass, PhanDeprecatedTrait, and PhanDeprecatedInterface on the class directly inheriting from the deprecated class, trait, or interface. (#972)
  Stop emitting that issue when constructing a non-deprecated class inheriting from a deprecated class.
• Include the deprecation reason for user-defined classes that were deprecated (#2807)
• Fix false positives seen when non-template class extends a template class (#2573)

Language Server/Daemon mode:

• Fix a crash - always run the language server or daemon with a single analysis process, regardless of CLI or config settings (#2898)
• Properly locate the defining class for MyClass::class when the polyfill/fallback is used.
• Don't emit color in responses from the daemon or language server unless the CLI flag --color is passed in.

Maintenance:

• Warn if running Phan with php 7.4+ when the installed php-ast version is older than 1.0.2.
• Make the AST caches for dev php versions (e.g. 7.4.0-dev, 8.0.0-dev) depend on the date when that PHP version was compiled.
• Make the polyfill support PHP 7.4's array spread operator (e.g. [$a, ...$otherArray]) (#2786)
• Make the polyfill support PHP 7.4's short arrow functions (e.g. fn($x) => $x*2)
• Fix parsing of some_call(namespace\func_name()) in the polyfill
